I was wondering if an arduino mega has enough proccesing power to make chess moves I know enough programming to do it but is it possible .
No, if you read the section about "One player" the Arduino is running a "lazy evaluation" system to make moves. I think the Arduino Mega has enough memory to play chess, you just need to write the code.
I have read it but does the arduino think and move.
It's already been done by our very own Patrick McCabe!
